Key takeaways
- Space games invite players to explore, pilot, survive, trade, solve, or fight across an unfamiliar setting. The free experience should include a meaningful destination and enough systems to understand the game. Monetization should not sell the only fuel needed to continue an ordinary session or conceal essential navigation behind payment. Optional purchases work when they expand the journey without replacing it. SEELE IAP keeps purchases explicit: players choose optional content, spend Koin, recharge if the balance is insufficient, and receive the described item without changing the complete free core.
Preserve the sense of discovery
Space games invite players to explore, pilot, survive, trade, solve, or fight across an unfamiliar setting. The free experience should include a meaningful destination and enough systems to understand the game. Monetization should not sell the only fuel needed to continue an ordinary session or conceal essential navigation behind payment. Optional purchases work when they expand the journey without replacing it.
Package ships, signals, and missions clearly
Ship paint, engine trails with unchanged performance, cockpit themes, companion drones used as cosmetics, soundtrack sets, and named mission packs are legible offers. A star-map expansion should identify its regions or mission count. If an item changes mechanics, describe that effect and test it against free progression. Avoid mystery cargo, misleading rarity, and premium counters to ordinary enemies.
Use the hangar for Koin decisions
A hangar, mission board, or post-flight debrief provides a calm purchase point. Show the exact item, its contents, Koin amount, and confirm and cancel actions. After confirmation, make the new ship style or mission visible. When Koin is insufficient, the player can recharge and return to the same selection. This supports purchase revenue without interrupting a launch, landing, or combat decision.
Verify navigation and owned content
Test the complete free route, reload purchased missions, and inspect effects against dark and bright backgrounds. Review rights for planets, ships, audio, and character designs; avoid references that imply a third-party franchise. The SEELE IAP hub defines the supported Koin boundary. The action guide covers combat fairness, and the simulator guide covers systems-heavy content packs.
Record a complete free mission, navigation and effect readability, mission-pack scope, ship-cosmetic parity, and restoration after reload before the hangar catalog is approved. Keep the review notes with the release record so later catalog edits can be checked against the same free-play and delivery expectations.
Frequently Asked Questions
What can space games sell with IAP?
Ship cosmetics, trails, cockpit themes, soundtrack sets, and clearly scoped mission or star-map packs can add optional value. For space games, verify the description, Koin amount, delivery, and restore behavior before publishing the offer. Confirm this behavior again after a clean browser reload.
Should fuel for normal play be paywalled?
No. A credible free journey should not stop because ordinary continuation fuel is available only through payment. For space games, verify the description, Koin amount, delivery, and restore behavior before publishing the offer. Confirm this behavior again after a clean browser reload.
How does insufficient Koin work in a hangar?
Keep the selected item visible, offer a recharge choice, and return the player to that same selection afterward. For space games, verify the description, Koin amount, delivery, and restore behavior before publishing the offer. Confirm this behavior again after a clean browser reload.
